Brooks GS 15 Limiter
A device which reduces gain when the input voltage exceeds a certain level.

Blending
1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance.
2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are not panned extremely left or right.

Foldback
A European term for the signal sent to the stage monitors in a live performance.
